This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 arising from an application for Notebook Computer Housing Assembly Capable of Extending Functions earlier filed in the Korean Industrial Property Office on 8 Dec. 1995 and there duly assigned Ser. No. 47938/1995.
The present invention pertains to a compact, portable, and lightweight expansion module that both physically and electronically attaches peripheral units to a host notebook or laptop computer.
The notion of attaching an expansion unit to a notebook or laptop computer to enable the laptop or notebook computer to have access to peripheral devices is not new. There are numerous references that contain such portable designs for expansion modules. For example, U.S. Pat. No. 5,459,637 for a Portable Notebook Computer Expansion Adaptor to Ma discloses a portable notebook computer with an expansion adaptor. Ma has an electrical connector socket positioned on the bottom side of a base portion of the notebook computer that connects with an electrical connector on the top side of the expansion module. Ma, et al. '637 does not contain the U shape holder guide nor does it contain buckles. Instead, a strap is used to hold the base portion of a notebook computer onto the expansion module.
A second example is shown in U.S. Pat. No. 4,969,830 for a Connection Between Portable Computer Components to Daly, et al. whereby a hand held portable computer that is secured to a peripheral or a expansion module in a snap arrangement. A multiple contact bus connector positioned on the bottom portion of the notebook computer mates with the top portion of an expansion module. A latch member of the expansion module is hooked onto an opening in the notebook computer, fastening the notebook computer to the expansion module. Daly, et al. '830 uses the expansion module to connect peripheral devices such as more memory, disk storage, or additional battery power to the notebook computer.
Japanese patent 404195507 to Ideno discloses an expansion module for a notebook computer containing a hooking mechanism for physically binding the expansion module to the notebook computer. The hooking mechanism is positioned about a pivot on the expansion module and pivotally rotates to hook or catch a latch part on the base portion of the notebook computer.
The notion of having the peripheral devices built into the notebook computer itself is also not new. By having a compact dick random access memory (CD-ROM) drives or a microprocessors built into the base portion of the body of a notebook computer, the need for an expansion module in some circumstances has been avoided. For example, U.S. Pat. No. 5,572,399 for an Information Processing Apparatus Having CD-ROM Device to Shirato et al. discloses a notebook computer having a CD-ROM disk drive built within. The CD-ROM disk drive is accessed by lifting up the keyboard of the notebook computer. No expansion or extension boards are used to accommodate this peripheral device. In addition, Shirato et al. '399 accommodates a second drive unit in addition to the CD-ROM disk drive device. Thus, the prior art demonstrates that it is unnecessary to require an expansion board or an extension card to have a notebook computer connected to a CD-ROM disk drive. In addition to Shirato et al. '399, U.S. Des. Pat. No. 375,086 for an Electronic Computer to Kondo shows, in FIG. 11, an ornamental design for a laptop computer with a CD-ROM disk drive built within.
What is needed is a better mechanical juncture between the notebook computer and the expansion module containing the peripheral devices. A better mechanical or physical juncture will result in a better electrical juncture between the notebook computer and the expansion unit. This better mechanical juncture is made up of three, instead of four points of contact between the notebook computer and the expansion unit. In addition to the two buckles, the present invention contains a holder guide which serves as the third and last point of contact between the two units. Because the holder guide is a continuum of points, there is no pivoting, and the notebook computer is more securely fastened to the expansion board than as shown in the prior art.
It is therefore an object to provide an expansion module design for a notebook computer.
It is also object to provide a notebook computer and expansion unit combination containing a more secure mechanical and electrical connection between the two units than disclosed in the prior art.
According to the present invention, a portable notebook computer housing assembly capable of extending functions comprises a slim type notebook computer having a housing consisting of an upper part and a lower part with its bottom having a first set of data signal connectors, and a functional extension case having a front side provided with fastening means and a rear side with a holder guide to mount the slim type notebook computer. The functional extension case is equipped with a second set of data signal connectors on the top side. The slim type note book computer is fixedly mounted on the functional extension case with the first set of data signal connectors connected to the second set of data signal connectors, with the two buckles fastened on both sides of the front portion of the notebook computer, and a holder guide in the rear of the functional extension case which holds the entire rear edge of the notebook computer into place.
A more complete appreciation of this invention, and many of the attendant advantages thereof, will be readily apparent as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, in which like reference symbols indicate the same or similar components, wherein:
FIG. 1 is a perspective view for illustrating a slim type portable notebook computer;

Referring to FIGS. 1-2B, the housing of a portable notebook computer 30 consists of cover 22 having display panel 22a and base portion 24 having keyboard 24a. Bottom side 26 of base portion 24 is provided with first set of data signal connectors 27 for connecting with external devices, as shown in FIGS. 2A and 2B. Also provided on the upper surface of base portion 24 are a pair of fixing holes 24b symmetrically positioned near both the left and the right side of the base portion 24.
A functional extension case 40, as shown in FIG. 3, is provided to have a front side equipped with buckles 34 and a rear side with a U-shaped holder guide 32 to mount notebook computer 30 as shown in FIG. 4. Buckles 34 are designed to be held by latching recesses 24b of the upper surface of base portion 24 of notebook computer 30. Functional extension case 40 is also equipped with second set of data signal connectors 36 to be connected with the first set of data signal connectors 27 on the bottom of base portion 24 of notebook computer 30. Functional extension case 40 is also provided with a bay 38 for mounting an auxiliary device such as compact disk read only memory (CD-ROM) disk drives. Functional extension case 40 also contains a microprocessor unit for use by notebook computer 30.
Buckles 34 consist of a pair of resilient strips 33 perpendicularly bent. Each of the resilient strips 33 has one end shaped in a curved grip 34a to be held by a latching recesses 24b, and the other end shaped as a pivot loop 34b rotatable about hinge 40a mounted on functional extension case 40.
As shown in FIGS. 4 and 5, notebook computer 30 is mounted on functional extension case 40 with the rear end being inserted into U-shaped holder guide 32. First set of data signal connectors 27 provided in the bottom of base portion 24 of notebook computer 30 are connected with second set of data signal connectors 36 provided on the top side of functional extension case 40. Curved grips 34a of resilient strips 33 are pivoted to be held by latching recesses 24b of base portion 24 of notebook computer housing 30. Separation of notebook computer 30 from functional extension case 40 is accomplished by detaching the resilient strips 33 of buckles 34 from latching recesses 24b and by separating first and the second set of data signal connectors 27 and 36 respectively from each other.
